HARNESS-MAKERS TOOL.

SPECIFICATION forming part of Letters Patent No. 386,801, dated July 31,1888.

(No model.)

To all whom, it may c0ncern:

Be it known that 1, WILLIAM G. BUNKER, a citizen of the United States,residing at Portage, in the county of Columbia and State of \Visconsin,have invented certain new and useful Improvements in Harness-MakersTools; and Ido declare the following to bea full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form apart ofthis specification.

As is well known, the staples in the hames of heavy team-harness arefrequently broken, when the harness is taken to the harnessmaker for theattachment of new ones.

Heretofore in securing a new staple to the hame it has been customary toplace the head of the staple in a vise with the legs projecting upward,then to pass these legs through the hame and rivet their ends. In doingthis I have found it difficult to hold the staple immovably in the jawsof the vise, as in the process of riveting it would be driven downbetween them and would then have to be readjusted before the work couldbe completed.

The object of my invention is to produce a tool for harness-makers whichwill support the staple in the jaws of the vise firmly and immovablyduring the process of securing it to the hame.

In the drawings, Figure 1 isa side elevation with a portion of the hameand a portion of one of thejaws of the vise broken away, showing thetool, staple, and hame in position in the vise. Fig. 2 is a perspectiveview of the tool, and Fig. 3 a vertical section of the same through lineto w of Fig. 2.

In the figures, A represents the tool; B, a hame-staple; O, the hame,and D the vise.

The tool A is made of iron or other suitable metal, cast in one piece,and in the form clearly shown in Figs. 1 and 2. Its back side is fiat,with a strong shoulder, a, projecting from its upper end, as shown inthe same figures. Its front side is provided with a semicircular recess,b, in which there is a strong pin, 0, arranged as shown. This recess isopen at the top, its semicircular portion being arranged as shown. Theportion of the tool in which the upper end of the recess terminates isflat, forming an even bearingsurface in front of the shoulder a. Inusing this tool it is placed between thejaws of a vise, D, with itsshoulder a resting upon the inner jaw. The staple B is then placed inthe recess of the tool, with its head or curved cnd resting upon thesemicircular recess, and with the pin 0 projecting through it, as shownin Fig. 1. The face of the pin 0 is in the same plane with the face ofthe tool. The jaws of the vise are then closed tightly together and thelegs of the staple are passed through the holes in the hame 0 providedfor that purpose, all as clearly shown in Fig. l. The ends of. the legsof the staple can now be riveted down upon the hame without driving thestaple down between the jaws of the vise, since the shoulder a of thetool, resting upon theinnerjaw of the vise, furnishes an immovablesupport and its semicircular recess an even bearingsurface.

Having thus described my invention,what I claim is A harness-makeflstool made of one piece ofsolid metal provided with a shoulder 011 itsrear side and a semicircular recess on its front side, with pin 0therein for supporting a hamestaple in the jaws of a vise in the processof riveting the staple to the hame, as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.
